Mountain Lion supports airplay mirroring to a hi-def TV. Unfortunately, my late 09 iMac is too old to have that capability. I downloaded a free trial version of AirParrot which allows my "older" computer to airplay. However, I found the resolution so poor that it 's not feasible to use Archicad that way (37" 1080p tv). I suspect even ML's airplay is the same. Has anyone with a newer machine tried it? How does it look?
